pantophobia (n.)

"morbid fear of everything," attested by 1848 in medical journals for a psychological condition described as "monomania, with fear and terror," from Greek pantos, neuter genitive of pas "all" (see pan-) + -phobia. Earlier (by 1819) it was noted as an old word for "hydrophobia, rabies." Related: Pantophobe; pantophobic.
